MK-677 and Testosterone Interaction

Avoid
Mechanism-based 64% confidence

MK-677 and Testosterone have a potentially harmful interaction with 64% confidence. Both MK-677 and Testosterone carry hepatotoxic risk. Combining hepatotoxic compounds significantly increases liver damage potential. If unavoidable, include liver support (TUDCA/NAC) and monitor ALT/AST frequently. These compounds primarily affect different organ systems.

Compound Profiles

MK-677

Ghrelin Receptor Agonist | Oral Growth Hormone Secretagogue

Selectively binds GHS-R1a receptors in hypothalamus and pituitary, triggering pulsatile growth hormone release while maintaining natural circadian patterns..

Half-life: ~24 hours Typical dose: Start 12.5mg daily, increase to 25mg based on tolerance growth hormone, weight loss, sleep

Testosterone

Anabolic-Androgenic Steroid | Primary Male Sex Hormone

Testosterone exerts its effects primarily through binding to the intracellular androgen receptor (AR), forming a hormone-receptor complex that translocates to the nucleus and modulates gene transcription. This drives protein synthesis in skeletal muscle (anabolic effect), stimulates erythropoietin production in the kidneys to increase red blood cell mass, promotes osteoblast activity and bone mineral density, and regulates libido and cognitive function.

Half-life: ~8 days (cypionate) Typical dose: 100-200 mg/week (TRT) anabolic, sexual health, metabolic
